Anyone have keccak wisdom to share?

So I'm trying maxcoin mining and am not getting quite the hash I was expecting. I was getting 3.5mhs on scrypt and am expecting about 2ghs on keccak, but am only coming in at 1.65ghs. It seems that the keccak cgminer tops out at I 14… is that right?

I've got 4 x Gigabyte R9 290 and they love high intensity and a single thread. They're not really digging low intensity with multiple gpu threads. I typically run xI: 500 and TC: 30719, but am now doing I: 14, TC: 8192 and gpu-threads: 2.

Hi folks. Please post feedback on any dealings with me. Thx.

I’m adding cards to my rig and am having some difficulty. I’d be very appreciative for any help. I have been running 1 R9 290 at 880khs for a couple weeks. I’m trying to add 2 additional R9 290’s, but they are not recognized by my system. The first card is still recognized and mines fine at 880khs, same as before. I can switch the cards and they each work, one at a time, but not together.

I had it recognizing 3 cards previously, but then went down to 1, now going back to 3. The cards are all Gigabyte Radeon R9 290 GV-R929OC-4GD. It shows only 1 GPU in sgminer, MSI Afterburner and only 1 display adapter in the Device Manager. I even booted to BAMT and it only sees 1 GPU.

I reinstalled sgminer and AMD drivers (after using Display Driver Uninstaller to remove the old ones). I’ve tried different risers. I've tried plugging each of the new cards one at a time. I’ve tried plugging the cards into the second 16x slot on the MB. All without success.

Thanks in advance.


I’m running:

MSI 970A-G43
8GB RAM
Win 7 x64
1 Gigabyte Radeon R9 290 GV-R929OC-4GD directly on MB
2 Gigabyte Radeon R9 290 GV-R929OC-4GD on powered 1x to 16x risers
SGminer 4.1
13.12 beta drivers

I am executing setx GPU_MAX_ALLOC_PERCENT 100 and setx GPU_USE_SYNC_OBJECTS 1 before launching SGminer.

My config:

   "failover-only": true,
   "xintensity": "500",
   "vectors": "1",
   "worksize": "256",
   "lookup-gap": "2",
   "thread-concurrency": "30719",
   "gpu-engine": "1002",
   "gpu-memclock": "1500",
   "gpu-powertune": "20",
   "gpu-threads": "1",
   "auto-fan": true,
   "temp-cutoff": "90",
   "temp-overheat": "85",
   "temp-target": "80",
   "queue": "0",
   "scan-time": "1",
   "expiry": "120",
   "api-port": "4028",
   "log": "5",
   "temp-hysteresis": "3",
   "kernel-path": "/usr/local/bin"

So I'm trying out using xintensity instead of intensity. I've had good results so far, but I have a question I hope someone can shed some light on.

How high does xintensity go? I haven't seen an significant difference in khs going from 500 to 1000. Does it actually cap somewhere?

I’m setting up my first rig and am having some difficulty. I’d be very appreciative of any help. Yesterday I unpacked 3x R9 290’s and got them all to run 500khs each (2 on the board and 1 on a powered riser). I know that’s low, but was hoping to tweak the config the next day.

I let it run for about 4-5 hours and everything seemed fine. Temps were all under 90. I let it run overnight and when I got up, it had a black screen.

Now when I test them 1 at a time, I have 1 card that does 500khs, 1 that does 175khs and 1 that crashes the PC just after the Starting Windows screen. Could I have killed the cards somehow?
